在Attribute Directives 属性型指令文章中,我们学习过了指令。指令是没有 HTML 和 CSS 的组件,它单纯用于封装 JS 的部分。 这一篇我们将继续学习另一种指令 -- Structural Directive 结构型指令。 就代码而言,Structural Directive 和 Attribute Directives 是完全一样的,只是用途不同,因此
Structural directives enable you to use an element as a template for creating additional elements. Creating structural directives requires a knowledge of<template>elements, but they're easy and extremely powerful once you undrestand the concepts.

Angular 2 中,在 common 模块里内置了 3 个 Structural Directive:NgIf,NgFor 和 NgSwitch。和 Angular 1.x 有很大不同的是,Angular 2 提供了通用的星号 DSL (类似于 *prop="something")来实现自定义表达式语法,而 Angular 1.x 只能自己靠正则匹配。其中,在 Structural Directives 和Template Syntax 部分对这...
Structural directives change the layout of the HTML document by adding and removing elements. They build on the core features available for attribute directives, described in Chapter 15 , with additional su
Content projection and structural directives This section describes the techniques used to perform DOM manipulation in Angular. DOM manipulation is based on the following ideas: An Angular template that encodes a chunk of HTML to be inserted and possibly repeated several times somew...

Water is an essential resource for sustaining humanity and life in general. Nowadays intensive pollution issues, and consequently lack of water quality in many areas in the world have raised awareness about the importance of water. Therefore, many conventions, directives, and protocols related to bet...
Because this step mainly involves element-wise processing of large arrays it is easily parallelised using a few fine-grained OpenMP [36] compiler directives. The computational platforms In this study, computational experiments were carried out using four different computational platforms, representing ...
